GAS-FIXTURE.

Specification of Letters Patent.

Application led June 9, 1909.

Patented Jan. 11, 1910.

Serial No. 501,027. v

fixtures of the character disclosed in Letters Patent Number 917,446 grantedto me April 8, 1909, in which a number of gasV burners are arranged around and connect with a common central casing, as in a chandelier, and in which the casing has a controlling valve for the gas supply to the light-s and carrying and feeding a revoluble gas lighter.

The present invention has in view a construction of this nature in which the lighter as it is revolved moves the controlling valve to turn on the gas to the several lights or burners in successive order, the How of gas in each burner starting atthe time the burner is reached by the lighter.

The invention further contemplates a construction of the lighter such that the liow of gas therethrough will lbe automatically diminished as the lighter passes in the intervals between the several burners, and also the diminishing of the flow of gas to the burners as they are lighted, until the lighting of the lastburner.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in lall the views.

Figure 1 is a side elevation of a chandelier constructed in accordance with my invention; Fig. 2 is a central vertical section of the same; Fig. 3 is a vertical central section through the lower portion of the fixture, showing the parts in a relatively different position from that shown in Fig. 2; Fig. 4 is a fragmentary horizontal section of the fixture taken through the upper portion of the controlling valve; Fig. 5 is a side view of the upper' portion of the controlling valve; and Fig. G is a side view of the lower end portion of the shank of the valve casing.

The gas fixture in the embodiment of the invention shown has a valve casing provided with a depending tubular shank 10a, the bore of the shank forming a continuation of a conical valve seat in the upper portion of the casing, at the top of which the casing connect-s with the main supply pipe 11 through the intermediary of a reducer 12. Radiating from the casing opposite the valve seat and arranged at the same elevation or in the same horizontal plane are a number of nipples 13, each having an at- -tached tubular arm 14 at its outer end, leading to and carrying a burner or llght 15, the alternate arms being shown to be relversely curved to the remaining arms,

whereby one-half of the burners are supported from the base and the other half from the top, thus producing an ornamental appearance. This ornamentation is further carried out by inclosing the valve casing 10 and nipples 13 by a shell 16, as well as a portion of the main supply pipe, the remaining portion of the latter being covered by a tube 17, made in two sections, with an ornament 18 extending between and clamped between them. These ornamental features form no part of my present invention but are simply illustrated and described for the reason that they arel features of the chandelier as constructed in practice.

An outletopeningl 19 leads from the val-ve seat of the casing to each nipple 13, the points at which t-hesel openings pass from the valve seat being arranged one below the other in passing in one direction about the casing, whereby no two .of said openings are arranged in the same horizontal plane. These outlet openings are preferably formed in the walls of the casing, as best shown in Fig. 2, from which it can be seen that the upper outlet opening is drilled or otherwise formed in the casing at the top of the re'- -cess, receiving the inner end of the nipple',

and in the lowest and all other outlet openings out of alinement with the nipple, recesses are formed by drilling an intersecting` vertical and horizontal hole in the walls of the casing, and plugging up the outer end portion of each hole by a screw or other suitable device 20.

Revoluble within the casing is a controlling valve Q1 having a. shank 22 extending from the head of the v'alve through and a substantial distance below the lower end of the tubular shank 10a, the valve having a gas passage 23 passing from the top and terminating short of its lower end, that portion of the passage within the head of the valve being enlarged or counterbored, as clearly shown in Figs. 2 and 4. The head of the controlling Valve is of conical const-ruction to contorni to the seat in the casing. w1th the enlarged portlon arranged at the top. and has a number of outlet openings passing through the side troin the inner' ing inerges into a cireuniterential groove in I the side otl the valve, as best shown in Fig. l

'-l. the inner wall ot which is' eccentricallv arranged with respect to the valve. gradually reducing the width ot the groove 1n passing' troni the slotted portion. with the i lnost contracted portion of the groove coni necting with the bore otl the valve through i an aperture 25. The gas openings or outlets below are likewise formed. with the corresponding apertures 25 arranged successively closer to the opposite edge or side of the outlet until the two bottoni outlets are reached, where, as best shown in Fig. 5. in the case of the upper outlet. the grooved portion extends in the opposite direction, and the lower outlet is in the torni ot a small aperture. Vly this disposition oit the outlets in the valve. when the latter in the position shown in Fig. l. all ot the outlets ttl in the valve casing are lapped. and by revolving the f'alve to the right. the upper outlet 2l uncovers the top outlet 19. and a t'ull tlow ot gas passes through the passage afforded by the connecting nipple 1? and arm lst. to the attached burner. Ou a continued revolution ot' the valve in the saine direction. the next lower opening uncovers the outlet in the casing of the next adjacent light. and this is continued until the gas is turned on to all of the burners. at which tiine the apertures of the outlets 2l are in register with the outlets l5) ot' the casing. ln nioving the valve to this position, a t'ull tlow ot gas is initially given to each burner in successive order and thereafter gradually dilninished until the outlets 19 are reached by the apertures 25. when a full flow of gas again given to all of the burners simultaneously. this obviously being the case by reason ot' the inner walls of the grooves leading troni the slots gradually approaching the periphery ot' the valve.

At the lower end portion of the shank 2Q ot the valve. a laterally-extending tubular arm 26 connects below the shank 10a ot the casing and is in communication with the passage The outer end portion of the arni '26 is provided with a valve QT. and at a point beyond the valve carries an upwardly-extending tubular arm 28 having a pilot burner l l l 20 at its outer end, arranged at the outside and in the path of the burners ot the several lights. (ln the lower end portion ot the shank 22 ot the controlling valve 2l.. is slidably carried a knob 30 having a counterbored lower end port-ion. in which is arranged a spring' Ill. the spring bearing on the knob and on the head oli a screw 32 threaded into the lower end ot the shank 22. and tending to torce the knob to an elevated position. The under side of the knob is closed by a plug 3l having an attached chain 35 provided with an operating ring 363. by which the knob may be drawn down to the lower limit ot its n'ioveinent. The knob in its upper position seats against the lower end ot the tubular shank l0, and is provided with a spring-pressed pin 3T entering a recess in the said shank when the coi'itrolling valve ot the gas supply is in its cut-ott position, as shown in Fig. '-l. 'lhe outer portion of this recess is V-shaped as shown in Fig. G to adniit ot the revolution of the knob in one direction only. The knob is slotted to pass around the tubular arni or pipe 26. above which it carries a laterallyextending` 'T-shaped arin 38. the lower end ot which is slotted to engage over and lock with the pipe 26. and the upper portion serving as a guide tor a rod 39. the latter being normally forced inwardly by a spring 4 0 bearing on its head 41 and pressing said head to a wheel l2 lixed to the lower end portion of the tubular shank 10F'. and having' ribs or Canis t3, equal in number to the ninnber of lights of the chandelier. The wheel is adjustably secured to the casing shank by a set-screw or other suitable device el-l. adinitting` of the proper location ot the wheel relatively7 to the burners. The outer end portion of the rod 39 is operatively connected to the lever 45 ot the valve 27. such that when the rod is 'forced outwardly. the valve is t'urther opened and the flow ot gas to the pilot burner increased; the valve. when the rod occupies its innerinost position. being only slightly opened. lVith the spring-pressed pin 37 of the knob 30 in engagement with the tubular shank 10a. the supply valve and attached lighter are locked against rotation. By7 however, drawing the knob downwardly. the spring-pressed pin is lowered sutlieiently to strike the inclined edge ot. the recess in the tubular shank, and will ride outthereon when the knob is turned.

Assuming the lighter to be lighted. and the controllingvalve tor the gas supply iu the position shown in Fig. -l-. ou revolving the lighter to the right. the head ot the rod 39 rides upon the adjacent rib or cani -l-Il. increasing the tiow of gas to the pilot, which shoots up a Haine. adjacent to one of the burners, as indicated in dotted outline in Fig'. Q. At this time the slotted side ot the Ystantaneous lighting, notwithstandingthat i top outlet of the controlling valve has been moved sufficiently to uncover the-outlet of the burner opposite the' pilot, and the outlowing gas consequently lighted. On' moving the pilot to the neXt burner, the head of the rod passes off of the cam and the flow of gas to the lighter diminished until the next burner is reached, at which time the flow of gars through the lighter is again increased and the neXt lower outlet opening of the valve passes into register with its respective outlet i n the valve casing. This is continued until the pilot reaches the last burner, at which time a full flow of gas passes to all of the lights, the latter brighteniiig up simultaneously. This gives the effect of inthe lights are lighted successively, the initial flow of gas to each'burner being full, to facilitate the lighting operation.

By reason of the particular locking mechanism for the valve, it will be impossible to turn the valve in the wrong direction in lighting the several burners. l

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
